Shoei CNS-2 Photochromic Shield

Transitions® adaptive sunwear products have a range of light transmission levels, all optimized for the specific activity the product is designed for. Specifically, the SHOEI® Transitions® adaptive shield:
• Non-activated — virtually clear
• Activated — darkens to a 15% light transmission level at 72º Fahrenheit and 23º Celsius
• Full activation in two minutes
• Fades to 50% transmission in two minutes
• Like all Transitions® products, the shield blocks 100% of UV rays
